Hello, I am running into a strange problem using Qmail-LDAP (and a series of other qmail patches) in a new installation. We have one qmail ldap install which has been running for over a year now, but obviously it is using older versions of the patches. I am hoping that perhaps someone has run into this problem before and can help out. What happens is that everything will roll along perfectly for a while, with mail being delivered quickly and properly. Then, an incoming message will fail to be delivered and generate an error like this one: 2001-06-11 11:04:37.100715500 delivery 17: deferral: Out_of_memory_in_qmail-lspawn./ Once that happens, subsequent incoming messages will do the same thing for a while. And then, just as suddenly as it started, it will go away and messages will be delivered normally again, including the previously deferred ones which had been queued for redelivery. I'm using the Qmail-1.03, the 0501 LDAP patch, the revised (and working) 0501 Dash patch for EZMLM, SMTP after Pop, SMTP Auth, Long DNS, and Qmail Queue. I did some tracing of qmail-lspawn with strace, and found that the out of memory error is always triggered in a pair of system calls like this: old_mmap(NULL, 1209446400, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory) brk(0x501cb000) = 0x8060000 old_mmap(NULL, 1209446400, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = -1 ENOMEM (Cannot allocate memory) brk(0x501cb000) = 0x8060000 I can't tell where in the code this is originating, but judging by what comes before in the strace, it is talking to the LDAP database. Could this perhaps be triggered by a bug in OpenLDAP (we're using 2.0.6?)
